Description

Dahlia Penhill Watermelon is a dinnerplate dahlia that commands attention with its oversized, ruffled blooms and mesmerising hues. Each flower, measuring an impressive 25–30 cm across, combines soft blush pink, warm coral, and hints of creamy ivory with a delicate undertone of watermelon red. The petals twist and curl in an irregular, artistic manner, giving the flower a wild, romantic appearance that feels both refined and natural.

Growing to a height of up to 120–140 cm, this variety is supported by sturdy, upright stems and complemented by lush, dark green foliage. It makes an ideal focal point in borders or cutting gardens, where its towering stature and dramatic blooms create a sense of grandeur. Flowering from midsummer through to the first frost, Penhill Watermelon ensures your garden remains vibrant throughout the growing season.

What sets Dahlia Penhill Watermelon apart is its unpredictable beauty. No two blooms are exactly the same, with subtle variations in colour and petal formation giving each flower a one-of-a-kind charm. This dynamic quality makes it a favourite among florists and gardeners looking for unique, statement blooms. Its petals seem to glow in the golden light of dawn or dusk, further enhancing its ethereal presence in the garden.

Despite its delicate appearance, this dahlia is robust and reliable, thriving in full sun and well-drained soil. Its sturdy stems make it ideal for cutting, allowing you to bring its extraordinary blooms indoors, where they will steal the show in any floral arrangement.

Supplied as high-quality tubers, Dahlia Penhill Watermelon is straightforward to grow, rewarding British gardeners with a season of unforgettable beauty.
